Title: Vehicle wheel and disc brake assembly
IPC: F16D65/18
Filed: 1950-01-25
Abstract: 688,382. Disc brakes; vehicle wheels. DUNLOP RUBBER CO., Ltd., WRIGHT, J., and BUTLER, H. J. Jan. 17, 1951 [Jan. 25, 1950], No. 1908/50. Classes 103 (i) and 144 (ii). A disc brake for a vehicle wheel comprises a non-rotatable housing straddling an annular disc which engages and rotates with a wheel, and covering a portion only of the disc and provided with at least one pair of co-axial cylinders disposed one on each side of the disc, pistons slidable in each cylinder and a pad of friction material interposed between each piston and the disc, whereby frictional engagement is effected between the disc and pads when fluid pressure is applied to the cylinders. In the embodiment shown in Fig. 1, a disc 13 attached to a wheel hub 4 is engaged on either side by friction pads 20, 29 which are forced against the disc to brake the wheel by pistons 18, 27. The pistons slide in axiallyaligned cylinders 17, 24 formed in a U-shaped member 16, carried on a stationary axle housing 5. Three pairs of cylinders 17, 24 are provided in the member 16 each having friction pads and being disposed at the same distance from the axis of the wheel and parallel thereto. All of the cylinders are connected together and to a common supply of pressure liquid for actuation of the brake. A rod 31 is attached to one piston and projects, through a seal 34, beyond the closure member 25 of the cylinder 24 and enables the amount of pad wear to be determined. In a modification, one pair of axially aligned cylinders house friction pads operated by a mechanical linkage, Fig. 5, actuated by a hand brake. The friction pads 39 are forced against the disc 40 by pressure plates 41 which are moved towards one another by levers 43, 44 interconnected by a rod 42. In the further embodiment shown in Fig. 8, two pairs of axially aligned cylinders, comprising pistons 75, 76 acting on friction pads 78, are formed in a stationary member 72 which embraces a rotating disc 70. A well-based wheel rim 64 is secured to the wheel web 59 and to the brake disc 70 by bolts 67 which pass through depressions 65 in the flange 62 of the web. Relative rotation of the rim and web is prevented by square washers 68 having a pair of opposite tapering sides one of which engages the web 59 opposite a depression 65 and the other of which engages a depression 66 in the rim 64. Annular shields 81, 82 cooperate to isolate the braking surface of the disc 70 from road dirt. In a further embodiment, Fig. 6 (not shown), two brake discs have pads between them engaged by a common cylinder. In one embodiment lightening holes are provided around the periphery of the disc which holes also reduce heat transmission to the wheel.

Abstract: 788,484. Resilient mountings. BOURGOIS, J. Jan. 20, 1956 [Jan. 22, 1955], No. 1980/56. Class 108(3) An elastic shock absorber or suspension device comprises two parts 19, 21, relatively movable and connected by means of a deformable block 3 having a cut-away portion 4 of flared or tapered configuration the lips 8; 9, of which, are made to approach one another and come into contact to an extent which increases with the load, and present a curvilinear profile which determines the spring rate of the device. In Fig. 9, the part 19 comprises two portions 19, 20 rigidly connected together and secured to opposite ends of the block 3. The part 21 comprises a stirrup connected to a middle portion 10 of the block 3. The cutaway portion 4 is engaged by two plates 13, 14, having curved end portions 15, 16, adapted to engage a circularly hollowed out portion 5 at the inner end of the cut-away portion 4. A lower screw 18 may be rotated to adjust the degree of pre-tension in the portion 10 of the block 3. An upper screw 18 may be adjusted to vary the abutment characteristics of the surfaces 13, 14 in relation to the lips 8, 9, of the block 4. In a modified construction (Figs. 7 and 8, not shown) the lower screw 18 is dispensed with and the plates 13, 14, are articulated adjacent the parts 15, 16. In a further modification the parts 19 and 20 constitute the relatively movable parts, the stirrup 21 being omitted. The block 3 then has a U- shape, and in their relative movement the parts 19, 20, move towards or away from each other to bendthe limbs of the U about its rounded portion. In the 'latter modification the plates 13, 14, may be omitted (Figs. 1-3, not shown). In Fig. 10, the plates 13, 14, are replaced by a frusto-conical shaped abutment 22 which is in adjustable screw-threaded engagement with a rod 23. The abutment 22 may alternatively be of cylindrical form. Lateral bulging of the material of the block 3 may be resisted by mounting washers on each end of a bolt passing through the hollowed out portion 5 (Fig. 11, not shown). In Fig. 13, a bolt 29 disposed within the hollowed out portion 5 of the block 3, is of split formation and is expandable by the action of frusto-conical members 33, 34, mounted on a threaded spindle,35.

Title: An Improved Process for Resharpening the Cuts of Old or Worn Files.
Inventor: LORENZETTI FRANCESCO
IPC: C23F1/06
Filed: 1917-02-12
Abstract: 110,340. Lorenzetti, F., and Longhi, I. Oct. 13, 1916, [Convention date]. Files.-Files are renovated by the following process. The files are first cleaned by means of a wire brush and steel point and then placed in a bath of sulphuric acid containing 1 part of acid to 4 parts of water and allowed to remain for 10 hours. After washing and drying they are placed in a vessel of water and sufficient sulphuric acid is added to cause the temperature to rise 15 degrees C. After 10 to 15 seconds the files are dipped into freezing water to restore their temper, and again washed and dried. They are then placed in a vessel containing a piece of lead, and a solution of nitric acid and common salt is poured in. This sharpens the teeth of the files and leaves a deposit of lead upon them to give them a new appearance. After an immersion of 10 to 30 seconds, the files are washed in freezing water and dried. They are then immersed for 5 to 20 seconds in a solution of oxalie acid and after washing and drying are treated with a solution of sulphate of iron and then washed in lime-water to restore them to their original colour and prevent rusting.
